Beauty is obviously subjective. But you want to know what isn't? Science.
Due to human genetic variation there's no such thing as a woman who looks phenotypically unique or non-common to the rest of the general population. Everyone place/area on earth has phenotypes that is common to them- so whatever type of woman(Brazilian, trini, habesha, dominican etc) YOU consider exceptionally attractive(or "exotic") looks common in the area where they are from AND any city in a heterogeneous society.
Show me an IG thot or model who looks exceptionally attractive to you, and if you can, show me a picture of her face without make-up/eye lashes/filters/fake hair and I can show you a million regular women who look similar and are on par with her.
Hell I'm confident you look better without makeup than some of the "exceptionally attractive" woman you idolize.
